The lucky-number has become increasingly popular in daily life of modern sociality. For example, the number eight means big money which people like most, while the number four means death.
Some people believe lucky numbers so deeply that they will afford a telephone with numbers without four and others which is bad in their mind. They argue that the lucky-number really can bring good luck, and, at least, no evidence testifies they can not.
As far as I am concerned, there is no such relationship between the numbers and lucky, for the reason that numbers their self are given certain meaning for the purpose of application of mathematic. And, in addition, man should not depend on lucky which, in their mind, the numbers gives them.
幸运数字在现代社会日常生活中已变得越来越受欢迎。例如，数字8意味着人们最喜欢的发财，而数字4则意味着死亡。
一些人深信幸运数字，他们只接受没有四和其他在认知中不好的数字之外电话号码。他们认为幸运数字真的.能带来好运，至少，没有证据证明它们不会带来好运。
就我而言，数字和幸运之间不存在这种联系，因为出于应用数学的目的数字被赋予了特定意义。此外，人们不应该依赖那些在他们看来数字会给他们的幸运。
